" STAPLE DRIVER.

Application filed February 28, 1923. Serial No. 620,578.

To all whom it may concern:

Be it known that: I, Tnonas TfRoon- BERG, a citizen of the United States,.residing at Montevideo, in the county of Chip- 5 pewa and State of Minnesota, have invented ce'rtain new and useful Improvements in Staple Drivers, of which the following is a specifieation.

My invention relates to staple drivers, land the object is to provide'an inexpensive and easily operated, etlieient device of said kind.

In the accompanying drawing.-

Fig. 1 is a side elevation of the device with staples in it. V

Fig. '2 is-a left hand end view of Fig. 1.

Fig. 3 is a right hand end view of Fig. 2, showing how it drivesa staple into wood.

Fig. this a bottom view of the lower right hand cornerof Fig. 1.

Fig. 5 is a side' view and Fig.5 .is an end view of one of several clips holding the staples ready' to be quickly placed in 2 the driven. p 4 r Referring to the drawing by referent-e numerals, 7 designates the main frame which may have a wooden handle 8, and is fixed at 9 and lfirespeetively to a .hori zontal frame bar 11 and a short horizontally flat frame portion 12 having an aperture 13 through Wlllt'll the staples escape one at atime when beingdriven.

Each staple is driven downward by a flat punch 14 formed at the lower end of a plunger 1:": having a pin 16 to li'mitits upward movement-and a head 17 to strike on when driving a staple. and a spring 18 holding the plunger normally in raised position. The punt-h 14 is guided also by a clip 19 secured lly two s 'rews 20. one of which holds also a'linger 21. whose flint-- tion is to hold one; end 222 of a long rontraction coil spring 23. said end of'the spring extending through a hole 2} in the frame Its rear end has a finger catch '28 'and its.

front and serves to move the staple 29 forward against the vertical port on 7 of the 7. The other end of the spring is securedframe 7 so as to be ready to be driven by the punch 14.

The staples are held down on the bar 11 by a guiding bar 30 having one end secured at 31, the other end at 32 (see Fig. 1).

33 is a channel strip (see Figs. 5 and 6) used as a clip for holding a number of, say about 50 staples at a time. ready to be slipped upon the upper edge of bar 11. One end of each clip is provided with guards 34 to prevent the staples sliding, out at that end.

The clips are filled with staples either in the process forming the staples or by some inexpensive automatic devioe (not shown) and when each clip is full 3. rubber hand 35 is slipped over the clip and the staples to hold the latter in place until wanted.

In the operation of the device small staples.= like those used in window shades and window screens may be driven home b v a blow of the hand upon the cap 17, but for larger staples a mallet or hammer may be used upon the head 17. As soon as the plunger is released ofeach blow it is raised again by the spring 18. and when the bar 11 is empty or nearly empty of staples, the operator pulls the follower 27 to about the position 27. the spring 2.? being long and limber enough for such movement of the follower. A ("1) 33 is then dropped in straddling position upon the bar 11, as at 33". and its rubber band or like means 3.3 out or removed and all the staples swept from the slip and in between the staple holding bar 11 and its guard tn'p30. This done the follower is replaced on bar ll. where spring 25 will constantly pull it against the new supply of staples.

What I t-laim is: i

1. staple driver having an open frame forming a horizontal staple holding bar, a ertical body portion extending in about; right angles upward from the front end of the horizontal bar. and a curved handle connecting said two bars. a plunger'slidable in the vertical body portion and having its upper end provided with a head and a spring engaging said head to raise the plunger,

means limiting the raising of the plunger. the lower end of the plunger forming a punch arranged to drive one staple at a time throiigh a slotted hole in the frame close h llu rum vml nl' iln- Maple suppnrling hm". :1 guiding strip fixml nuar al ow tlm staple -u |pm-Llng I'm in mwvnt raising of [he sluplw.
